Direct Current Theory

Direct Current (DC) Theory explains how electric charge flows consistently in one direction through a circuit, unlike alternating current which periodically reverses direction. In DC systems, electrons move steadily from the negative terminal to the positive terminal of a power source, such as batteries. This steady flow allows for stable voltage levels and is ideal for electronic devices, circuits, and systems requiring constant power. Understanding DC theory involves grasping concepts like voltage, current, resistance, and how they interact to ensure reliable and predictable electrical performance.
